The moon was created in a huge planetary collision 4.5 billion years ago. It was initially 22,000 km away, and an Earth day was 5 hours long. Due to tidal action, the moon has gradually moved away to 400,000 km, and slowed the Earth’s spin to a 24 hour day.
Point Nemo is over 1000 miles away from civilization, making it the least accessible place on Earth. The closest people to Point Nemo are usually astronauts aboard the ISS. Also, it is used as a ‘cemetery’ for spacecraft, because life cannot survive near it due to a lack of nutrients.
There are planets considered more habitable than Earth, based on potential for biodiversity. Scientists have identified 24 such planets so far.
November 2, 2000 was the last time all humans were on the planet together. Since then at least one person has remained on the international space station.
Carl Sagan convinced NASA to turn the Voyager Spacecraft towards earth and take the iconic “Pale Blue Dot” photo nearly 4 billions miles away from earth.
Those who see Earth from space experience “The Overview Effect:” A remarkable sense of connection with the rest of the human race, and a desire for world peace.
Due to gravitational time dilation the core of the earth is approx. 2.5 years younger than surface. Higher gravitational potential causes time to move faster. For example, over the course of earth’s history, a clock at the top of Mt. Everest would be approx. 39 hours fast than at sea level.
Superabundance is the belief, that no matter how many natural resources humanity uses, the planet will continuously replenish the supply. This, actually is the myth.
Because of the movement of the Earth’s tectonic plates, Australia is drifting so fast that they plan to adopt a moving GPS system by 2020 to compensate for the changes.
The average person will walk approximately the distance of 3 times around the planet in their lifetime.
L = Sd x D / C
L = (7500 steps) (0.672 m) x (71 years x 365 days) / 40 075 000 m
L = 3.26 laps
